The apparatus of this invention is adapted to be used in combinationwith a typewriter or printing machine wherein a plurality of paper websis passed through the machine in adjacent relationship for producingmultiple copies of desired information. Particularly, the apparatus isadapted to control the movement of carbon sheets which are placedbetween adjacent paper webs to produce the multiple copies. The paperwebs have printed faces which are repeated upon the surface of the webto produce bill forms or the like which can be fed through a typewriterin a continuous web. The carbon sheets are adapted to be used severaltimes and since the paper webs are continuous, the carbon sheets must bemoved with respect to adjacent forms after the information has beenplaced upon one of the for s taken along 4 so that the carbon sheetswill be disposed adjacent the subsequent form upon the web when the formis carried over the platen of the y writer. The webs can be arranged ina fan-fold pack with or without a perforated fold line to permitseverance of individual forms from the webs, or they can be flat webswith a perforation line between adjacent form faces.

In this invention the carbon feeding apparatus is constructed as anattachment which can be associated with any conventional typewriter. Asshown in Figure 1, the carbon feeding apparatus H! is shown in positionadjacent a conventional typewriter IS. The typewriter I5 consists of theusual frame I l supporting a carriage l2 which in turn supports a platenI3 having a knob ll for rotating the platen l3 manually. The standardkeyboard [6 is carried by the typewriter l5. In all respects thetypewriter i5 is of conventional construction and it is thereforebelieved further description of this apparatus is not necessary, Theassociation of the platen I3 and the carriage l2 of the typewriter withthe carbon feeding apparatus ill for producing cooperative actiontherebetween will be hereinafter more fully described.

The carbon feeding apparatus l3 consists of a frame ll for supportingthe carbon feeding apparatus Ill in adjacent relationship with respectto the typewriter IS. The frame II has a base I! adapted to rest upon atable or other support. The base [3 has a cast body i3 secured theretoby-means of a bolt 26. A bolt 2! is threaded into the body 19 and isadapted to engage some part of the rear wall of the frame ll of thetypewriter ii for positioning the frame I! and thus the carbon' feedingapparatus with respect to the typewriter l5. A hook 22 is pivotallymounted on the body [3 by a pivot pin 22-. The shank of the hook 22extends through the pivot pin 23 into threaded engagement with the thumbscrew 23. The hook 22 is adapted to engage the rear wall of the frame llof the typewriter ii at a point adjacent the bolt 2| to secure the frameI I against the head of the bolt 2|. The thumb screw 24 tightens thehook 22 upon the typewriter frame H.

The frame H for the carbon feeding apparatus has two rods 25 and 26extending transversely thereof and in parallel relationship. A frame 21is carried upon the rods 25 and 26 by means of rollers 28 and 23 inengagement with the rods 25 and 26 respectively. The rollers 28 and 29are suitably secured to the frame 21 and have arcuately curved surfaces30 and 3| for engaging the surface of the rods 25 and 26. The frame 21is thus supported vertically adjacent the rods 25 and 26 for movementalong the rods as caused by the typewriter carriage in a manner to behere-' inafter described. A U-shaped member 32 is secured to the frame21 and extends around the rod 26 as a safety measure to prevent therollers 28 and 29 from leaving the rods 25 and 26.

The frame 21 supports the bed plate 33 in the carbon feeding apparatusH]. The bed plate 33 is constructed in two part consisting of an uppersection 34 and a lower section 35. The upper bed plate section 34 is aflat plate having channel shaped edges 36 (see Figure 15). The lower bedplate 35 is also a flat plate having channel shaped edges 31 (see Figure15) which are of sufficient dimension to encompass the channel shapededges 36 of the upper bed plate 34 to permit the channel shaped edges 36of the bed plate 34 to slide within the channel shaped edges 31 of thebed plate 35 whereby the longitudinal dimen- -of ,the thumb screws 56.

40 extending from the end thereof which project.

downwardly into the recess 38 in the upper bed plat portion 34 toprevent paper webs passing 7 'over the bed plate 34 from becomingentangled with the edge 4| of the lower bed plate portion 35. The bedplate .portions 34 and 35 are retained in properly'adjusted relationshipby mean of a Y 46 extending therethrough to prevent movement of theclamp42 with respect to the plate 45. A

threaded rod 41 extends from the clamp 42 through the plate 45. threadedupon the rod 41 for binding the channel shaped edges 36 and 31 of thebed plate .por-

'.tions 34 and 35 between the clamp 42 and the supporting plate 45.

The supporting plate 45 has a pair of threaded rods 49 extendingtherefrom upon which thumb screws 58 are threaded. The rods 49 slidewithin slots 5| provided in a supporting plate 52 extending from theframe 21 whereby the bed plate 33 is supported upon the frame 21 and canbe adjusted vertically with respect to the same by proper location ofthe rods 49 within the slots 5| and binding the rods into positionthrough means The bed p1ate 35 is provided with a supporting plate 45adjacent each side edge thereof for engagement with a supporting plate52 extending upwardly from the frame 21. v

A paper guide member 53 extends from the lower bed portion 35 and ismovable with respect to the same. This paper guide member 53 is providedwith a rolled edge 54 which is positioned between the under side of thelower bed portion 35 and a retaining-member 55. The retaining member 55has a portion thereof in spaced parallel relationship to the bed plateportion 35 and has a hook portion 56 adapted to be engaged by the rollededge 54 of the paper guide member-53 when it is desired to remove thepaper guide member 53 from its adjacent position with respect to'theback plate 51 of the typewriter. Normally, the paper guide 53 engagesthe back plate 51 to direct paper webs passing over the bed plate 33toward the platen |3.

To provide connection between the carriage I2 of the typewriter and thebed plate 33 of the carbon feeding apparatus for moving the bed A thumbscrew 48 is that the frame 68 floats upon the pins 63 and 64. Thiarrangement is such that the movement of thecarriage |2 of thetypewriter vl5 is not transmitted directly to the bed plate 33 forcingthe carriage of the typewriter to move the entireweight of the carbonfeeding apparatus-upon each successive motion, but rather the frame 68moves with the carriage and'through means of the floating action betweenthe frame 60 .and the bed'plate 33, the bed plate-33 can follow up themovement of the frame 60 in a slightly lagging relationship.

The arms 6| and 62 of the name so are connected together by means of awriting or erasing table 18 to maintain the arms in substantial parallelrelationship. A tie rod ll aids in holding the arms 6| and 62 in theirproper relationship. A roller 12 is carried upon a plate 13 which ispivotally mounted upon the arm 6| by means of the pivot pin 14. Theplate 13 has a pin 15 ex: tending therefrom through a slot 16 providedin the arm 6|. A thumb screw 11 is threaded upon the pin 15 toretain'the plate 13 in a properly adjuste'd position. The roller 12engages the platen l3 of the typewriter for supporting the frame 68 inadjacent relationship to theplaten I 3. Adjustment of the plate 13permits adjustment of the frame 68 with respect to the platen 3. Asimilar roller 18 is provided upon the arm 62.

To retain the frame 60 in proper relationship with respect to thecarriage i2 of the typewriter adjusting screws 19 and 88 are carried bythe arms 6| and 62 respectively for engaging the side walls or somestationary part of the carriage l2 of the tween the arms 6| and 62 forarranging paper webs extending through the typewriter in longitudinallyaligned relationship when a typed form is completed and is to be tornfrom the continuous web. This means consists ofa pair of rollers 8| and82 suitably mounted in the arms 6| and 62. The rollers are arranged inparallel relationship, the upper roller 82 having th extending shaftsthereofdisposed in the slots I15. A tear-off and web aligning blade 83is pivotally carried upon an actuating lever 84 which is pivoted vuponthe pivotpin 85. One of the actuating levers 84 is provided upon each ofthe arms 6| and 62 of the frame 68 and is interconnected by means ofa-rod 86 to form the handle for the levers 84.

A spring 81 is connected between the lever 84 and plate 33 in unisonwith the carriage 2 a frame 66 is provided. The frame 66 consists of apair of arms 6|" and 62 which are pivotally mounted upon pins 63 and 64projecting from the sup porting plates 45 secured to the upper bed plateportion 34. Helical springs 65 and 66 are positioned upon the pins 63and 64 and have their inner ends in engagement with the arms 6| and 62respectively. The spring 65 and 66 are retained under compression bymeans of screws off and aligning blade 83 out of engaged relationshipwith respect to the rollers 8| and 82 whereby paper webs can pass freelybetween the tear-off and aligning blade 83 and the rollers 8| and 82.

To' retain the paper webs passing over th bed plate/33 in engagementtherewith and to prevent buckling of the paper when the webs are movedin a reverse direction by means of the platen l3 of the typewriter apaper bale 88 is placed in engagement with the lower bed .plate portion35. The fiiaper bale 88 consists of a wire frame 89 having a plate 90secured toadjacent parallel arms! 9| and 32 of the frame 89. A leafspring 93-is secured to the plate 98 and is adapted to extend angularlyupwardly therefrom. The free end' of the leaf spring 83 has an upwardlybent portion 94 which forms an angl with respect to the main body of theleaf, spring83 to form a 3 plate a. The springs 65 and 88 are balancedso V-shaped channel which engages the writing table 10. The upwardtension of the leaf spring 93 retains the bale 88 in engagement with thebed plate 33. The degree of tension of the paper bale upon the bed plate33 can be regulated by means of an adjusting screw 95 which is inthreaded engagement with the leaf spring 93 and bears against the plate90 of the paper bale 88. A pointer I16 is slidably carried upon the bale88 that is adapted to be positioned upon the bale so that it willprovide means whereby an operator can gauge the position of a fold orperforation line with respect to the tear-off or aligning blade 83. I

When a completed form is to be removed from the continuous web of formsthe platen I3 is rotated by the operator to feed the webs I42, I48 andI44 downwardly over the bed plate 33 and upwardly past the rollers 8Iand 82 until a perforation or fold line in the webis in alignment withthe pointer I16. A fold line 180 is-then in position adjacent thetear-off and alignin blade 83 as shown in Figure 16. The blade 83 isthen moved inwardly against the webs, the blade being directed somewhatdownwardly toward the roller 8! to engage thewebs I42, I43 and I44 in a.manner that they will be caused to shift with respect to one anotherwhen the webs are retained between the blade 83 and the roller BI andthe blade rides upwardly over the surface of the roller 8I, as shown inFigure 17. The blade 83 strikes the perforation or fold line in the websand thus causes them to shift and be aligned thereby. 1 y

The blade 83 is then retained in position as shown in Figure 18 so'thatwhen an operator grasps the forms extending above the roller 83 they canbe pulled forwardly to sever the forms from the webs, the upper roll 83moving upwardly to prevent binding of the forms between the rollers 8|and 82.

The carbon feeding mechanism consists of a roller 96 bearinged in aU-shaped support bracket 91 which is secured to the under side of theupper bed plate portion 34. The surface of the roller 96 is positionedadjacent an opening 98 provided in th uppermost edge of the bed plate 34which is adapted to be engaged by a paper web for retating the roller 96when the web is moved inwardly into engagement with the roller 96 bymeans of a roller I32. The roller 96 has a spur gear 99 secured upon thesame shaft which bearings the roller 96, the spur gear 99 thu rotateswith the roller 96. The spur gear 99 is in meshing relationship with aspur gear I bearinged in the support bracket 91 by means of the shaftIN. The gear I00 carries a pin I02 adapted to engage an arm I03 carriedupon a shaft I04. The shaft I04 (see Figure 3) is bearinged at its'inner end upon the shaft IOI which extends within an axle bore providedin theshaft I04. The opposite end of the shaft I04 extends within anadjusting mechanism for regulating the operation of the carbon feed inaccordance with the length of form being used upon the same, whichmechanism will be hereinafter described. The arm I03 is secured to theshaft I04 by means of a clamp I05 and is thus stationary with respect tothe gears I00 unless rotated by th shaft I04. A torsion spring I06surrounds the shaft IN and has one end thereof in engagement with thesupport bracket 91 and the opposite end secured to the gear I00 wherebythe gear is constantly urged in a direction to place the pin I02 againstthe arm I03.

A carbon detent I01 is secured .adiacent each end of a rod I08 bearingedin the depending wall 09 of the upper bed portion 34. The carbon detentsI01 are secured to the rod I08 by means of clamps I I0. The detents I01extend through slots III provided in the upper bed portion 34 wherebythe ears II2 are adapted to be engaged by carbon bars II3 (see Figures 6to 10) which carry carbon sheets II4 adapted to be positioned betweenadjacent continuous paper webs. Each of the detents I01 carries a dogII5 pivoted thereto by means of a pin II6. A light spring is positionedbetween the dog H5 and the ear II1 extending upwardly from the detentI01 to urge the dog H5 in a forward position (as shown in Figure 4).

The carbon detent I01 has a ledge IIB adapted to engage a finger II9provided'on a clamp I20 Secured to a rod I2I bearinged in the dependingside wall I09 of the upper bed portion 34. The clamp I20 forms a leverextending from the rod I2I. A clamp I22 is secured to the'rod I2I from alever extending therefrom adapted to be enaged by the pin I02 secured tothe" spur gear I00. The clamps I20 and I22 provide a lever systembetween the pin I02 and the carbon detent I01 whereby the carbon detentis released when the pin I02 engages the clamp I22 to cause rotation ofclamp I20 with respect to the carbon detent I01.

The shaft I08 to which the carbon detent l01 is secured has a clamp I23secured thereto forming a lever extending therefrom. The clamp 1123 has.an arm I26 pivotally connected thereto by means of a pin I25 whichextends into engagement with a. clamp I26, the lever I24 being pivotedto the clamp I26 by means of the pin I21 (see Figure 5). The clamp I26is carried upon an arm I28 extending inwardly from a wire frame I29. Theclamp I26 in this instance remains sufficiently loose upon the arm I28to be bearinged thereon. A clamp I30 is secured to the arm I23 of theframe I29 and has a pin I3! extending therefrom into engagement with thebearinged I clamp I26.

The frame I29 carries a roller I32 positioned in substantially verticalalignment with the roller 96 to apply friction upon a paper web passingbetween the rollers I32 and 96. The Weight of the roller I32 and thframe I29 is such that the pin I3I normally engages the bearinged clampI26 so that the clamps I26 and I30 actuate the frame I29 as though thearm I24 was connected directly to the frame I29 for rotating the sameabout the arm I28 as an axis.

If, however, it is desired to prevent the roller I32 from engaging thepaper web, the mechanical arrangement provided by the clamps I26 and I30permit the frame I29 to be moved rearwardly manually with respect to theoperating mechanism. A stop I33 pivoted upon a support member I34 bymeans of a pin I34a (see Figure 4) is thrown rearwardly to permit theframe I29 to pass thereover and thus be thrown away from engagement withthe paper web passing over the roller 96.

The support member I34 is adapted to engage the edge of paper webspassin over the bed portion 34 to maintain edge alignment between thewebs. These support members-I34 are adjustable transversely of the bedportion 34 within slots I53 provided in the bed portion 34. J

When paper webs, which have been folded in accordion fashion, are passedover the upper edge of the bed plate 34, there is a tendency for the'ation of the apparatus.

folds in the webs to cause the roller L32 to lift sufficiently thatslippage is permitted between the roller 96 and the paper webs wherebythe measuring device is not properly operated. To maintain the rollerI32 in engagement with the paper webs alocking mechanism is provided forengaging the operating mechanism for the roller I32 when the paper websare moving in engagement with the roller 96. When the paper'webs aremoving over the roller 96 the position of the carbon feeding apparatusis as shown in Figures 4 and 8. 7

The locking mechanism for the roller I32 consists of an arcuately shapedarm I35 secured to a clamp member I36 which in turn is secured to theshaft I M (see Figures 11 and 12) The frame I29 carries a clamp I31secured thereto and having a pin I36 extending therefrom. 'Thearm I35has a hook I39 adapted to engage, the pin I38 to retain the frame I29 inposition with the roller I32 in engagement with the paper web passingover the roller 96. The arm I35 is rotated with the shaft I2I as theaxis of rotation so that when .the shaft I2 I rotates to position thecarbon detent I01 in the position shown in Figures 1 and 7, the rollerI32 is thereby placed in engagement with the paper webs passing over thero1ler-96, causing them to engage the. roller 96 to drive the same,thehoolr I39 lieing advanced into engagement with the pin I36 therebylocking the frame I29 in position with the roller I32 engaging the paperweb.

To manually release the locking mechanism (shown in Figures 11 and 12) afinger pad I40 is provided on the arm I35. By applying pressure, uponthe iln'gerpad I40 the shaft I2I will be rotated about its axis in arightward direction (as viewed in Figures 11 and 12) to release the pinI25 and thereby permit the roller I32 to be lifted from the paper webs.

The description heretofore presented sets forth the mechanicalarrangement of the carbon feeding apparatus. The diagrammatic figures, 6to 10, show the apparatus in various stages of operation. The mechanismis shown in various positions resulting from various movements and oper-The mechanism shown in these figures is somewhat schematic but-theoperational function is completely set forth.

Beginning with Figure 6, the apparatus is shown in a position wherein atyping operation can be performed upon a plurality of adjacent. paperwebs I42, I 43 and I 44 having carbon sheets II4 interleavedtherebetween. The carbon sheets 4 in this figure are shown in positionfor the typing operation and have been previously released from thecarbon detent I01 to permit the carbon bars H3 and the carbon sheets 4'to move with the paper webs I42, I43 and I44, as fed through thetypewriter by means of pressure engagement between the'platen I3 and theprescarbon detent I01 is rotated about .the axis ofthe shaft I03, andsince the detent I01 issecured to the shaft I03 the clamp I23 is rotatedin the direction of the arrow shown in Fi ure '1. The ear 2 of thecarbon detent I01 rises into the position shown in Figure I topositionits'elf in the path of the downward travel of the carbon barsII3 when their travel is reversed by reversing rotation of the platenI3. Rotation of the clamp I23 positions the arm I24 to cause rotation ofthe frame I29 in the direction of the arrow shown in Figure 7 wherebythe roller I32 is caused to engage the paper webs, I42, I43 and I44 andmove them into engagement with the roller96,

As can be seen from the position of the linkage between the shaft I06and the frame I29 a toggle arrangement'is provided thereby so that whenthe apparatus is in the position shown in Figure 7 there is a tendencyfor the carbon-detent I01 to be retained in the position shown .therein.

When the carbon detent I01 reaches the position shown in Figure 7 thelever linkage providedby'the clamps I20 and I22 on the shaft I2I tendsto rotate in a rightward direction; as indicated by the arrow, due tothe oil-balance of the linkage in that direction whereby the finger II9provided on the clamp I20 is positioned beneath the ledge IIB providedon the carbon detent I01 to lock the detent in the position shown inFigure 7. Also, the arm I35 engages the pin I36 as shown in Figure 12 tolock theroller I32 in position as shown in Figures 7 and 12.

The paper webs are moved rearwardly or upwardly along the bed plate 33until the above described operation is performed. If the operator of thetypewriter should run the typed form from between the platen I3 and thepressure rollers I a slight buckle will be given the paper webs (asshown at I54) to provide suiiicient spring I the finger us on the clampin engagement with the ledge II6 on the carbon de- 7 of paper webpassing over in the webs to force the ends thereof into engagement withthe platen I3 and the pressure roller I so that when the direction ofrotation of the platen I3 is reversed the paper webs will be caughtbetween the platen I3 and the pressure roller I to again send the samethrough the typewriter.

The mechanism is now in position to permit passage of the paper websI42, I43 and I 44 over the bed plate 33 without movement of the carbonsheets II4 so that the form which has been previously typed can beremoved from the typewriter and a subsequent form aligned. The beginningof this operation is shown in Figure 8. The showing of this figure issuch that the platen I3 is rotating in the-direction of the arrow,thereby moving the paper webs I42, I43 and I44 through the typewriter,but the carbon sheets I I4 are detained from movement since the carbonbars II3 are in engagement with the ear II2 of the carbon detent I01. Itwill be remembered that the roller I32 is in engagement with the paperwebs passing over the roller 96 so-that the roller 96 will be rotated bymovement of th paper thereover, due t the frictional engagement of thepaper webs with the roller 96. Rotation of the roller 96 causes the gearI00 to be rotated so that the pin I02 will be advanced in a leftwarddirection, as indicated by the arrow in Figure 8. The pin 102 would beadvanced and the clamp I20 in a leftward direction until tent I01. Thequantity the roller .96 before the'carbon detent I01 releases the carbonbars travel of the pin .Il2 from the arm I03 to the until it strikes theend of the-clamp I 22 rotating the shaft I2I is. moved out of I isequal-to the length of a printed form face and is measured, by the clampI22. The interval of time required for the pin to move from the arm I03to the clamp I22 and release the detent I01 thus regulates the length ofpaper web moved through the carbon sheets I I4 before they are releasedto permit their movement with the paper webs I42, I43 and I.

Movement of the paper webs I42, I43 and I over the carbon sheets III andthe carbon bars H3 produces friction tending to move the carbon barsdownwardly and thus move the carbon sheets with the paper webs. However,the carbon bars cannot move until the pin I02 has engaged the clamp I22and has rotated the clamp I20 suificient to release the carbon detentI01. When the carbon detent It? is released, frictional engagementbetween the paper webs and the carbon sheets will rotate the carbondetent I01 about the axis of the shaft I08 thereby causing movement ofthe arm I24 which results in lifting the roller I32 from engagement withthe paper webs passing over the roller 96. Release of pressure upon thepaper webs passing over the rollerv 96 stops rotation of the roller 96since the webs are released from engagement with the surface of therollerand will now be supported by the bed plate 3t spaced relationshipto the roller 96. The linkage between the carbon 'detent m and the frameI29 is such that the combined weight of the roller I32 and the frame I29retains the mechanism in the position shown in Figure 9 since the armI24 and the clamp I23 have now been thrown over center from the positionshown in Figure 8.

When the pressure is released from the paper webs the torsion spring Irotates the gear I00 to return the pin I02 against the arm I03 so thatthe measuring device is conditioned for the next operation.

The carbon sheets and the paper webs are now ready for advancementthrough the typewriter by means of the platen I3 and the pressurerollers III to permit the typed form to be removed from the machine, toali a subsequent form and to position the subsequent form in typingposition upon the platen I3. The transition from Figure 9 to Figureshowsthe paper webs advanced through the typewriter until a perforationor fold line between adjacent forms is adjacent the tear off blade 83.The operator rotates the platen I3 until a perforation or fold line isaligned with the pointer I16. This places a. fold or perforation lineadjacent the blade 83 as shown in Figure I6. At this time the pressurerollers I lI of the typewriter are released from engagement with thepaper webs passing under the platen I3. The blade 83 is then movedinwardly to engage the webs and align them. This is accomplished sincethe fold line between adjacent form faces is the weakest portion of theform and the adjacent folds will always tend to align one with the otherwhen a shart edged instrument engages the fold line and moves thew.v

same thereby.

arm I03 with respect to the clamp I22, andthus the travel of the pin I02regulates the length of paper web which passes between the carbon sheetsIII before they are again released to permit their advancement with thepaper webs. To adjust the position of the arm I03 the mechanism shown inFigure 13 is provided.

This mechanism consists of a worm wheel I45 secured upon the shaft I00which carries the arm I03 (as shown in Figure 3). The worm wheel I05carries a pointer I40 having an edge thereof adjacent a slot IA'Iprovided in the cover I48 for the adjusting mechanism. A worm I09 is inengagement with the worm wheel I05 and is carried upon a shaft I50bearinged in the cover I48. A hand wheel I5I is secured to the shaft I50and is disposed beneath an indicating pointer I52. Indices are placedupon the hand wheel I5I indicating fractions of an inch so that onerotation of the hand wheel I5I causes rotation of the shaft I04 toposition the arm I03 further from or closer to the clamp I22 to shortenor lengthen the form passing over the roller 95 before release of thecarbon detent I01. One rotation of the wheel I5I thus changes thesetting of the arm I03 to permit-one inch more or one inch less of webto pass over the roller 96 until the carbon bars are released.

Rotation of the worm wheel I moves the pointer I45 to indicate thenumber of revolutions of the hand wheel I5I and thus the number ofinches which can pass over the wheel 98 before the carbon detent NIreleases the carbon bars H3. The indices adjacent the slot It! thusindicate inches in length of the paper web so that by reading acombination of the indices adjacent the slot I41 and the indices on thehand wheel I5I an exact determination can be had of the length of formfor which the carbon feeding mechanism is set.

In order to use the typewriter in normal typing operation for singlesheet work the frame 60 can be pivoted upwardly upon the pins 83 and 60so that the frame will lie upon the bed plate 53. The paper bale 88 isremoved from the carbon feeding apparatus to permit the pivotal movementof the frame 60. The paper guide 53 is then moved upwardly until therolled edge 54 engages the hook portion 56 of the retaining member 55.When these operations have been performed the space above the typewriterplaten I3 and the back plate 51 of the typewriter is free andunobstructed so that paper sheets can be fed into the typewriter in thenormal manner.
